I bought a new watch after my old one's strap got broken. I opened the "watch" part of the watch and took out the LCD display. Here it is...

The upper one is the glass/plastic thingy. And the lower one was beneath the upper one in the "arrangement" (and isn't a part of this question). The thing is, when I press the glass/plastic one on its surface a liquid-rainbow kind of thing appears (one like you might have noticed a million times on LCDs), and when I touch the upper and lower edges of the glass/plastic, it lights up! I mean I see digits and other symbols on it as if the watch is still working just like before I tore it apart! And also it shimmers when viewed from different angles

You guys got any explanation??? I really need to know why this is happening!!!

I guess, it has to do with squeezing the liquid into the pre-defined cavities rather dragging it with an electric field. But I'm not sure. You can falsify your hypothesis by touching it with something else than your hand. Maybe, you will find something here.

LCD displays work by placing a nematic fluid between two electrically charged plates driven by a square wave. When the charge is directed across a given segment, it changes the shape of the molecule making up the fluid, which in turn changes how the molecules react to light. In the undistorted state, the molecules reflect light and look silvery. When distorted, they absorb light and look black.

Many nematic fluids are also sensitive to pressure, so when you press on the display, you are distorting the molecules and forcing them into the light absorbing state.
